Abstract: A data processing apparatus is coupled to receive call data records from a telephone network (4), for example an SS7 network. The apparatus (1) receives data records of different types having different formats. For each different type of data record, the apparatus (1) has a library (9, 10, 11 ) of type-specific functions associated with the particular type of data record. The apparatus (1) also has a set (8) of common functions available which contains functions that can be utilized for all types of data records, and for managing the system. Instructions are received by the apparatus (1), which indicate which type or types of data records are to be received and which functions are to be carried out on the data records. The apparatus (1) then creates a function list of the particular functions that are to be carried out before executing the particular functions on the received data records and then storing the processed records in a database (12, 13, 14).

Abstract: What is described in this case is a laboratory microchip having microspray means whose direction of spray can be altered. The microchip has a substrate 40 which has a channel structure provided on one side 41 thereof. On the other side (in the region of an edge of the substrate in the present case), there is a microspray tip 42. Substrate 40 is designed to be deformable particularly in a region 43, in which case the deformability may be achieved either by thinning the substrate material locally in this region 43 or by means of a linear perforation extending approximately perpendicularly to the plane of the paper. Alternatively, the deformability may be obtained by selecting a suitable material for the entire substrate. A microchip which has been bent in the manner indicated is shown in the bottom part of FIG. 3. The bending of the substrate which is shown has turned the direction of spray 44 of microspray tip 42 through 90°. The bending of the substrate may be permanent or reversible in this case.

Abstract: A window detector circuit for high frequency applications includes a differential amplifier that has two inputs which receive a differential voltage signal. A bias network, having a balancing node, connected between the two inputs. An output transistor, electrically biased by the balancing node, connected between power and ground. In operation, when the differential voltage signal is below a voltage threshold, the differential amplifier is turned off and current flows through the output transistor. When the differential voltage signal is at or exceed the voltage threshold, the differential amplifier turns on.

Abstract: A method of fabricating a diode device, such as a PIN diode, includes forming top and bottom regions of opposite conductivity types and includes anisotropically etching into the top surface to form a pit having side walls that converge with approach to the bottom surface. However, the pit does not extend to the bottom surface. In the PIN diode embodiment, the pit terminates within an intrinsic region that separates a bottom surface diffusion region from a diffusion region along the walls of the anisotropically etched pit. The anisotropic etching approach provides a degree of self regulation with regard to the geometries of the pit. A process flow of steps is described, which allows thicker and larger diameter wafers to be used in the formation of an array of such diode device.

Abstract: In a signalling network employing the SS7 signalling protocol, it is known to use masks to mine CDR stores in order to obtain data for analysis in respect of a particular customer of a communications network associated with the signalling network. However, the use of masks to mine the CDRs can result in the retrieval of unwanted CDRs or the omission of relevant CDRs. The present invention therefore provides a call monitoring apparatus that receives a CDR and accesses a reference database, comprising a list of customers and respective telephone numbers, in order to identify an association between the CDR and a given customer. Consequently, speed and efficiency of analysis of CDRs is increased.

Abstract: An imaging apparatus and a method of capturing and storing an image in digital form within a photosensitive area of the apparatus include integrating an array of memory cells within each pixel of the photosensitive area. Preferably, the memory cells are dual port memory cells, such that write operations can be performed in a parallel manner while reading operations are performed in a serial manner. In the preferred embodiment, each array contains a sufficient number of memory cells to store two digital words representing a photo signal and a reference signal. A comparator within each pixel operating in unison with a counter and a ramp generator captures the photo signal and the reference signal in digital form. The design of the imaging apparatus allows each pixel in the photosensitive area to capture and store the signals in a parallel manner.
